Doc Text:	A flaw was found in Jenkins. When triggering a build from the Jenkins CLI, Jenkins creates a temporary file on the controller if a file parameter is provided through the CLI’s standard input. Affected versions of Jenkins create this temporary file in the default temporary directory with the default permissions for newly created files. If these permissions are overly permissive, they may allow attackers with access to the Jenkins controller file system to read and write the file before it is used in the build.	Story Points:	---

Description Avinash Hanwate 2023-03-13 08:26:55 UTC

Jenkins 2.393 and earlier, LTS 2.375.3 and earlier creates a temporary file in the default temporary directory with the default permissions for newly created files when uploading a file parameter through the CLI, potentially allowing attackers with access to the Jenkins controller file system to read and write the file before it is used.
